How this service works
A simple, fully disclosed momentum signal from Chainlink on Base: current price versus the price 24 oracle rounds earlier, percent change, and a label (up / down / flat, threshold 0.5%). Pass ?pair=ETH-USD (default). The method is the whole product: no model, no secret sauce. Not financial advice.
Output
Returns the current price and the price from 24 oracle rounds earlier for the requested pair, the percent change between them, and a human-readable momentum label: 'up', 'down', or 'flat' (using a 0.5% threshold). All data is sourced directly from the Chainlink oracle contract on Base with no proprietary modeling.
Example use cases
Automated trading signal check
“Before my bot places a trade, check the Chainlink momentum signal for ETH-USD — tell me if it's up, down, or flat and by what percent.”
Portfolio monitoring alert
“I want to know if BTC-USD has moved more than 0.5% in either direction based on the last 24 Chainlink oracle rounds on Base — what's the signal right now?”
On-chain signal for DeFi strategy
“Pull the current price momentum signal for ETH-USD from Chainlink on Base — I need the percent change and the up/down/flat label to decide whether to rebalance.”

Endpoint
GEThttps://oraclepost.higgsfield.app/api/premium/signalWhen to prefer
Choose this endpoint when you need a transparent, on-chain momentum signal with no black-box modeling — purely derived from Chainlink oracle rounds on Base. Ideal for agents that need a simple directional label (up/down/flat) and percent change for crypto pairs without relying on centralized exchange APIs or proprietary signal providers. Best for ETH-USD or BTC-USD pairs available on Chainlink Base feeds.
Side effects
- Unsupported pair symbol returns an error or empty result
- Chainlink oracle unavailable or lagging causes stale data
- Base network congestion may delay oracle round data
- Missing or malformed 'pair' query parameter may return default ETH-USD or error
- Payment failure (x402) blocks access if USDC balance is insufficient
